Conclusion All IM, oral, and SL routes of administration of vitamin B12 can effectively increase the level of vitamin B12 without significant differences between them, as thought previously
A Vitamin B12 shot is a medical-grade intramuscular injection of cholecalciferol-quality, pure cobalamin (the active form of B12)
The clinic offers both intramuscular B12 injections and guided oral supplement protocols, matching the delivery method to each patients clinical presentation, absorption capacity, and diagnosis
In most cases, side effects are brief and disappear within a couple of days
